Simplify the following: \( \begin{array}{ll}\text { 2.1.1 } & \left(-2 x^{3} y^{3}\right)^{4} \\ \text { 2.1.2 } & -2\left(-4 x^{2}\right)^{2}+2\left(3 x^{2}\right)^{2} \\ \text { 2.1.3 } & \sqrt{49 x^{8}}+(2 x)^{4} \\ \text { 2.1.4 } & \frac{\left(3 x^{3}+2 x^{3}\right)^{2}}{5 x^{2} .5 x^{2} x}\end{array} \)

question 4. Solve \( 3 x+2=2+4 x \)

which of the following equations is not a linear function? 1) \( 2 y-3 x=1 \) 2) \( 4 x^{2}+y^{2}=4 x y \) 3) \( y=2 \) 4) \( x=2 \)

4. Make \( c \) the subject of \( g=\frac{c+3}{4+c}-7 \)

Add \( 5 \mathrm{a}-3 \mathrm{~b} \) and \( -5 \mathrm{~b}+3 \mathrm{a} \) the result is ...... \[ \begin{array}{l}8 \mathrm{a}-8 \mathrm{~b} \\ 8 \mathrm{a}+8 \mathrm{~b} \\ 8 \mathrm{~b}-8 \mathrm{a} \\ 2 \mathrm{a}-2 \mathrm{~b}\end{array} \]

Three consecutive numbers their sum is 48 write an equation express that is .... \( \begin{array}{l}3 x+2=48 \\ 3 x+4=48 \\ 3 x+3=48 \\ 3 x-3=48\end{array} \)
